Thanks! We tried to use in-game stuff as the tutorial. The baby starts under the table, so you know he can fit in tight places. During the portion where you can see enemies under the floor, you should need to turn from adult into the old man on your way back into a baby, so you can see the enemies do not follow you when you are old. The adult doesn't really have anything other than speed going for him, both him and the old man can climb on stuff.
